Application filed September 1'], 1891.

To all whom, it may coiz cerm Beit nov ,nthatLALBmWARTH, a citiin the county of Richmond and State of New York, have invented new and useful Im- Machines, of,

, This invention relates to certain improve, ments in cloth-cuttingmachinesin which circular knives-are used, said improvements being pointed out in the following specification Figure 1 is an elevation of the cutter-head, showingoneside. Fig. 2 is an elevation show 1 tirieir ithe cutteuhead. Fi sta 2:. vertic'al -section in the plane 00 m, Fig. 1. Fig. 5.is a similar section of a modification. Fig. 6 is a horizontal section in the plane 'y y, Fig. 5. Fig. 7 is a vertical section of the circular knife and itsbearing in the plane a .2, Fig. 2, on a larger scale than the previous figures. Figs. 8 and 9. are-detail views of the knife-bearing. .Fig. 10 is a'vertical section, and Fig. 11 is a side elevation, of another modification. Fig. 12 is still another modification.

In the drawings, the letter-A designates-the cloth-lifting foot-plate, from which rises the standard B, which carries. the circular knife 0. Theseparts form the cutter-head of a cloth cutting machine, and this cutter-head can be moved 'over the table 1 in the manner well known to those skilled in the art. 7

On the standard B is secured a hanger" D', and in order to be able to adjust this hanger up or down I secure the same to the standard by means ofa screw a, which passes through a. slot 12 in the hanger, said hanger being provided with lips c c, which engage the edge of the standard and serve to retain the hanger in the required vertical position. On the inner surface of the hanger isformed a circular recess d, which engages a cylindrical stud e, formed on the inner surface of a disk E,

(Figs. 2, 4, 7, and 9,) which is secured to the hanger by a screw f and which is prevented fromturning round byasteady-pin g,extend-" mg from the hanger and engaging a hole hin the disk, Figs. 7, 8,

and 9. In the h. nger and J n 0 wheels, so that when a revolving motion is through the interior of Serial No. 408,002, (No model.)

disk are formed circular recesses j for the reception of an absorbent materia L-snch as fin'e cotton waste, and into these recesses lead the hanger D and of the circular disk E are .chamfered ofhso that the knife can be made to cut through a pileot material, the depth of which is greater than the radius of the knife.

For the, purpose of imparting a rotating.

disk F, which engages one of the faces of the shown two circular disks F F, which are motion to the knife 0, I employ a frictionmounted on an arbor G; which has its hearings in a tube H, extending from a'platel,

which is'adjustabiy secured to a bracket 3,

carriedbythe standard B. On one end of the arbor G is cute. screw-thread to receive anut m, and if this nut is screwed up the disks F F are drawn up tight againstthe opposite faces of the knife, so that they are capable of transmitting motion to the same. On the'arbor G is mounted a pulley K, round which extends the driving-belt L. In the example shown in Figs. 5 and 6 the drivingdisks F F are mounted on vertical ashore,

', respectively, which are geared by cogimpartedto thearbor a rotating motion imparted to the knife 0 by the disks, which engage the opposite faces of theknife. 9 On the arbor f "is 'mounteda pulley which. cu-

gages the driving-belt. The arhors f f'- have their hearings in a f extending from the arbor G, which in this case is adjus'tably secured in the tube H, but has no revolving motion. It will be seen that in both exam ples the knife is geared with the driving-belt which'riscsfrom the standard B.

In the example shown in Fig. i the friction-disks F F are made detached from each other; but said disks can be connected toe.

a tubular casing M,

- common hub, as shown in Fig.10, and in that case I prefer to make said disks in the form of circular elastic j? 's, so that when the knife 01's forced in'betii'een them said jaws bear against the opposite faces of the knife with suificieut tenacity to impart motion to the knife when the'shaft G is caused to revolve.

through a pile of material of considerable use two disks engaging the the knife. v

N 1s a protector, which is adjustably secured tothe standard 13 and which extends down over one face of the knife 0.

What I claim as new, and desire to secure by Letters Patent, is-- I 1. The combination, with the cloth-lifting foot-plateadapted to be moved over the table which supports the matcriai to be cut and with the standardsrising from said foot-plate, of a circular knife carried by the standard, a shaft situated ahoivc the cloth-lifting footplate and carried by the standard, a frictional driving-diskmounted on this shaft and em gaging-she'knifmand means forirnparting to said shaft a revo ving motion, substantially as deswibed. y

Tne combination, with the cloth-lifting foot-piate adapted to be moved over the table which supports the material to be cut and with the standard rising from said plate, of a circular knife carried by the-standard, a shaft situated above the ninth-lifting" foot-plate and carried by the standard, two frictional drivi ng-disks mounted on this shaft and engaging the opposite faces of the knife, and means for impartingto said shaft a revolving motion, substantially as described;

3. The combination, with the cloth-lifting foot-plate adapted to be moved over the table which sunports the material robe cut and with the standard rising from the some, of a hanger secured to the standard, stud carried by said hanger,

mounted on said stud, a shaft situated above .the cloth-lifting foot-plate and carried by the standard, a frictional driving-disk mounted on this shaft and engaging the knife, and

vmeans for impartingto said shaft a revolving,'

motion, substantially as described.

4i. Thepombination, with the cloth-lifting foot-plate adapted to he moved over the table which supports the material to be cut and with the standard rising from the same, of a hanger secured to the standard, a disk E, securedto the hanger, a cylindrical stud extendingfrom this disk, a circular knife mounted on this stud between the disk and the hanger, a shaft situated above the cloth-lifting footplate and carried by the standard,a frictional driving-disk mounted on this shaft and engaging the knife, and means for imparting to said shaft a revolving motion, suhstantiall y as described.-

5. The combination, with the cloth-lifting foot-plate and with the standard rising from said foot-plate, of a hanger secured to the standard, a disk secured to the, hanger, ncircnlar stud extending from this disk, a circular knife mounted on this stud and between the disk and the hanger, rims l and grooves 3', formed on the inner faces of the disk and the hanger, a driving-disk engaging'the knife at a distance from its center, and means for imparting to said driving-disk a revolving motion, substantially as described.

,6. The combination, with the cloth-lifting foot-plate and with the standard rising from said foot-plate, of s circular knife carried by said standard, an arbor G, mounted in bracket attached to the standard, two driving-disks mount-ed on said shaft in planes parallel to the pi :e ofkthc' knife and engnging the opposite faces of the said knife, the clamping-nut nnand the pulley K, mounted on the arbor G and adapted to engage the drivlug-belt, substantially as described.

In testimony whereof vI have hereunto set my hand in the presence of two subscribing witnesses.
